piece size=1/x
\n" ); document.write( "cut into x pieces
\n" ); document.write( "1-(1/x) after Sue
\n" ); document.write( "(1-(1/x))-(1-(1/x)/5) after Nathan.
\n" ); document.write( "This is (x-1)/x - [(x-1)/5] after Nathan.
\n" ); document.write( "this is (4/5)(x-1)/x
\n" ); document.write( "Now, 4(x-1)/5x is left
\n" ); document.write( "After Jeremy takes 1/3, there is 2/3 of that left or 8(x-1)/15x left.
\n" ); document.write( "That equals 1/2
\n" ); document.write( "16(x-1)/15x=1
\n" ); document.write( "16x-16=15x
\n" ); document.write( "x=16 pieces ANSWER
\n" ); document.write( "after Sue, 15/16 is left
\n" ); document.write( "Nathan took 1/5 of that so that 12/16 pieces are left
\n" ); document.write( "Jeremy took 1/3 of that so now 8/16 pieces are left or half.
\n" ); document.write( "
\n" ); document.write( "
\n" );
